Comparative analysis of advantages and disadvantages of waterproof coil and wate

Due to the difference in material composition and appearance form of waterproof coil and waterproof coating, the characteristics, construction technology, applicable parts and application environment of the material are different. Jcdecaux waterproof engineers have made a comparison of the comprehensive performance of the two, and let consumers roughly understand what products they need.

Advantages:

Waterproof sheet - convenient construction, short construction period, no maintenance after forming, not affected by temperature, small environmental pollution, the layer thickness is easy to master according to the design requirements, the material calculation is accurate, the construction site management is convenient, it is not easy to cut corners, the layer thickness is uniform, and the base stress can be effectively overcome when the base layer is empty (when the base layer has a large crack, it can maintain the integrity of the waterproof layer).

Waterproof coating - any complex base can be made into a continuous integral waterproof layer; The equipment is simple and the construction technology is easy to master. The waterproof coating layer and the base layer have a 100% bonding surface (except for cracks, joints and other parts using reinforced layer empty paving method). The water leakage of the coating waterproof layer in the service life is mostly the base cracking width exceeding the extension of the waterproof coating, the cause of water leakage and the formation of water leakage parts are easy to find, and the warranty is very convenient, as long as a small amount of waterproof materials repair cracks and damaged parts. High quality waterproof coatings can be successful in waterproofing the back surface. Part of the waterproof coating can be constructed on the wet base and form a waterproof layer.

Cons:

Waterproof coil - it is necessary to measure and cut clothes according to the shape of the waterproof base. For the complex shape of the base, it is necessary to splice multiple pieces, and the bonding of the waterproof coil at the overlapping point is relatively difficult; Complete and absolute sealing will become the main problem, the biggest potential water leakage; Waterproof coil protection after construction and maintenance after water leakage is also a problem, any part of the penetration damage, degumming, leakage (even if it is only one), the entire waterproof function of its coherent level will all fail, if you can not find the damage and defect parts, then the local repair is impossible, then only rewaterproof.

Waterproof coating - coating requires a certain amount of time after physical and chemical reaction consolidation to generate waterproof layer; Some waterproof coatings produce harmful gas release during the curing process, which is harmful to human body. Some waterproof coating a waterproof layer of the completion of the need for multiple brushing, each brush to have a certain interval of time, so the final completion of the waterproof layer to a longer time; In the construction process of waterproof coating, site management is very important, jerry-cutting, shoddy production in the case of management negligence will have the opportunity to take advantage of; The thickness of the coating waterproof layer is determined by the number of coating passes during construction. In addition to the number of coating passes, the solid content of the coating itself is the determining factor of the film thickness.
